A complete grading plan should clearly illustrate existing and proposed site topography, and provide sufficient information to determine the limits of grading and disturbance. Per County Code Section 16.20.060, minimum grading plan requirements are as follows:

Grading plans must include the following on a 24" x 36" blueprint:

Name and address of property owne

Assessor's Parcel Number (APN)

Name and location of existing, adjacent streets

Vicinity map

Intended use or purpose of work

North arrow and scale of drawing

Site plan including entire parcel (APN) with area of proposed grading indicated and enlarged for clarity if necessary

Existing structures, utilities, trees, watercourses, or any other topographical features of interest

Details of proposed structures, including retaining walls

Property lines, setbacks, or building envelopes

Existing and proposed contours. Topographic information must be at a suitable scale to insure clarity. Minimum contour intervals are as follows:

Slope of Existing Ground

Contour Interval

0-5%

1

5-15%

2

15%

10

Note: GIS contours are not of sufficient accuracy to be utilized as base topography for grading plans.

Volume of proposed grading for both cuts and fills

Cross-sections of cuts, fills, building pads, and driveways (including property lines where appropriate)

Existing and proposed drainage facilities including culverts and other structures as appropriate

An adequate erosion control plan including appropriate details and specifications

Signature and stamp of civil engineer or architect

After review by staff, additional information and/or plan revisions may be requested to clarify the proposed scope of work and ensure that this work meets County Code requirements. To assist the preparer, a grading plan checklist is available that provides a more detailed list of plan check requirements. If desired, this checklist may be completed by the preparer and included with the grading permit application materials to help guide staff to the necessary information during plan check.
